Fecha de publicación: | 11-sep-2020 | Editor: | Multidisciplinary Digital Publishing Institute | Citación: | Biology 9(9): 1-16 (2020) | Resumen: | Menopause strongly increases incidence and consequences of obesity and non-communicable diseases in women, with recent research suggesting a very early onset of changes in lipid accumulation, dyslipidemia, and insulin resistance. However, there is a lack of adequate preclinical models for its study. The present trial evaluated the usefulness of an alternative method to surgical ovariectomy, the administration of two doses of a GnRH analogue-protein conjugate (Vacsincel®), for inducing ovarian inactivity in sows used as preclinical models of obesity and menopause. All the sows treated with the compound developed ovarian stoppage after the second dose and, when exposed to obesogenic diets during the following three months, showed changes in the patterns of fat deposition, in the fatty acids profiles at the different tissues and in the plasma concentrations of fructosamine, urea, β-hydroxibutirate, and haptoglobin when compared to obese fed with the same diet but maintaining ovarian activity. Altogether, these results indicate that menopause early augments the deleterious effects induced by overfeeding and obesity on metabolic traits, paving the way for future research on physiopathology of these conditions and possible therapeutic targets using the swine model. | Descripción: | 16 Pág. | Versión del editor: | https://doi.org/10.3390/biology9090284 | URI: | http://hdl.handle.net/10261/338813 | DOI: | 10.3390/biology9090284 | E-ISSN: | 2079-7737 |
